Rear/Diff/Speedometer questions

Hey Dan,

 

thanks for searching the net for me and actually finding some better infos than me!

 

What a coincidene! I am writing mails with J.Mitschke already. I found the JDRace.com page and got good qualified answeres to my BOP Rear.

And guess what: J.Mitschke has a 71SS Monte!!!

 

He also had a good explanation why my Potiac Tempest rear got in the Monte. He said in 1970 there were a lot of strikes going on, and the assembly lines took any GM rear that were available.

 

If anybody has rear end questions, I can recomend the JDRace.com page. They are specialised in GM muslecar rears only! And he takes the time in answering proper. Not like the so many standarised computer answeres I got from other sites.

 

And to your question on the option.

I assume it is the elecctric seat back lock. I think, but I am not sure, just playing puzzle, that it is the locking mechanism of the front seat operated by one of those 2 door pins. When I close the door the front seats lock, so they can't lean forward while driving. I hear a strong "click" when closing the door. It took a while to figure that out because all my friends want to ride in the front and we squeeze all in there. One time somebody got in the back and found the source for that click comin from the seat.

But I am not sure if I take that option wrong.

 

Oh, and my door edge guards are not there anymore... wink

 

My 8 Track AM player is stored safe. With time and money I want to sent it to a guy that fully restores the old GM radios and puts line in/out and other newer features in it with keeping the old tube/transistor mehanism alive. He only does old GM radios at his pace. I just hope I will be able to do so before these guys with their eligable knowlegde and experience all die.

 

To give you a price on him, a full service is not below 450-500USD. If anyone interested I can find that link and paste it here.

 

Back to my rear:

 

I belive it is less hazle to keep my rear also for the originality of my car. Since I am not planing on racing I won't abuse it too much.

Only at the red lights fuming my oponents of course! So maybe I have to spend more $$$ for internal parts, but that rear end is not a weak one for my purpose.

 

So long

Janin

Oh, and here a good reason for picking on Euro options on US cars...the two just don't work together:

 

A pic from my stock '2-barrel-Euro-castration-carb' in comparison to the eddi 600cfm I will put on....

 

I wonder how the car could even run with so little...

Glad you're finding the information that you need. Mr. Mitschke should join us here.

 

We put the same Edelbrock carb on our 71. You'll like it.

 

The seat back electric lock option, [st bk elec lk], is very, very rare. It was available, but not listed in the FGMCC tech pages for 1970.
